I originally had a lifeproof case. Made the phone too big and screwed with the ambient light sensor so I switched. I now have the Caseology Wavelength series case and it's great. Fits nicely, as a matter of fact someone thought it was part of the phone rather than an aftermarket case.
Fit's nicely and the gold trim on the one I bought matches the gold color of the phone. http://smile.amazon.com/Caseology%C2%AE-Wavelength-Textured-Cover-Shock/dp/B01BEH1QSW/ref=sr_1_4?ie=UTF8&qid=1460641930&sr=8-4&keywords=caseology+lg+g5
